` Claims'. f (01139-384) cords are sufciently water repellent to ensureThis invention relates' to the rmanufacture of woven fabrics in whichrelatively largetextile reinforcing cords are laid in one or more secetions of the fabric to give ysaid section or sections a required degreeof stiffness.

The object of the invention is to `provide an improved cord stiifenedfabric in which the reinforcingcords extend inthe Warp wise direction ofthe fabric and are ladlin place between woven yface andback plies lofthe stiffened section so y that the back of said section issubstantially as smooth and flat as theback of the unstiifened portionsof the fabric. y

Another object of the invention is to provide `a cord stiffened fabricin `which the stiffening that the stiffened sections ofthe fabric willretain their original stiffness after repeated Washings. l l

Another object of the invention is to provide a generally improved cordstiiened fabric in` which eachr stiffening cord comprises a braidedcovering enclosing a plurality of yarns twisted together to form thecenter or core of the cord,

said core and braided covering being preferably sized and then treatedwith a suitable Water `repellent finish. i

Proceeding now to a more detailed description reference will be had tothe accompanyingdrawing, whereinn Fig. l is a plan viewyof the improvedfabric lproduced in accordance With'this invention.

Fig. 2 is a` cross section through one of the stiiened sections of thefabric appearing in Fig.

u 1. In this View the various Warp, weft and binder y threads of thestiiened section are shown spread out to clearly illustrate the natureof the weave. Fig. 3 is a View illustrating the vmanner in which thefirst pick of the faceply of the stiffened` Fig. 7 is a" viewillustrating the constructionr of one of the stifening cords embodied inmy improved fabric.

The fabric appearing in Figi 1 comprises flexible sections 3 alternatingwith stiffened sections` 4 in which the reinforcing cords 5 areincorpo--` rated, as hereinafter explained. Any suitable Weave may beemployed in producing the iiexible sections 3 but the stiifened sections4 aretwoven so that each section includes a back ply 6 which forms theback covering of the stiffening cords 5 and a plurality of woven faceplies 1 which are secured to the back ply 6 bybinder threads 8 5 and 9to form individual front coverings for the cords 5. The manner in whichthe back ply and` the various face plies of eachcord stiffened sectionare woven and `secured together by the binder threads is clearlyillustrated in Figs. 2 to 6 nlo elusive. As here shown, the back ply 8is formed t by the weft threads III andl IIv and the warp threads I2 andI3. The weft threads I0 pass over the warps vI2 and underv thewarps I3,while the weft thread Il passes under: the Warps I2 u and over the warpsI3. It will also be noted that the two Wefts IIJ and II of the back plyare passed over all ofthe binder threads 8 and 9. Each face ply 1 isformed by the interwoven weft threads I4 and I5 and the Warp threads I6and I1. The weft threads I4 pass under the Warps I6, over the Warps I1,over the binder threads 8 and under the binder threads 9. The remainingface ply Wefts I5 pass over the face warps I6,

under the face Warps I1, under the binder threads 8 and over the binderthreads 9. It will thus be seen that each cord 5 is heldto the face ofthe l Woven back ply 6 by an individual cord covering formed by one ofthe face plies 1 of the Woven section and that eachof fsaidfface pliesis secured to the back ply 6 at opposite sides of the cord by the binderthreads 8 and 9.

With this method of Weaving, the back of the cord stiffened sections 4of the fabric are left substantially as smooth andflat as the back of35' the exible sections 3. In other words the cords 5 and the face plycord coverings 1 form outstanding ribs on the face of the back ply 6.

Another feature of theinvention resides in the construction of thestiffening cords 5. As shown in Fig. 7 each cord comprises a pluralityof yarns 6a twisted together to form a core enclosed by a` braidedcovering 6b. The yarns Ba; are sized separately to increase theirstiffness before being twisted` together to form the core. After the 45braided covering has been applied to the core, p

the cord, as a whole, is treated with a suitable size andthen given avsuitable water repellent finish which serves to hold the size in thecord so that it will retain its stiffness after the repeated Washings.,i Having thus described `my inventionwhat I claim is:

1. A'woven fabric made of warp threads, weft 'threads and stiffeningcord warps, the fabric k515 having a stiffened area and a non-stiffenedarea, the stiifened area comprising a back ply of fabric coveringv aseries of stiffening cords and a face ply surrounding each stiifeningcord on one side and holding it securely to the back ply, the stiffeningcords comprisingv a plurality of sized yarns tightly bound by a braidedcovering.

2. A Woven fabric made of Warp threads, weft threads, stiifening cordWarps, and binder threads, the fabric having a stiifened area and anon-stiffened area, the stiifened area comprising a back ply of fabriccovering a series of stiffening cords and ya face ply surrounding eachstiffening cord on o-ne side and holding it to the back ply, the cordcovering portions of the face ply being securely held to the back ply bybinder threads located at opposite sides of each stifening cord, saidstiifening cords comprising a plu rality of sized yarns tightly bound bya braided go covering.

which certain weft threads of the face ply pass under certain of thebinder threads and over the remaining binder threads, the remaining weftthreads of the face ply being passed over the first mentioned binderthreads and under the last mentioned binder threads.

4. A Woven fabric as set forth in claim 2 in which certain weft threadsof the facing ply pass under the binder thread at one side of astiffening cord and over the binder thread at the opposite side of thestifenng cord, the remaining weft threads of the facing ply being passedover the rst mentioned binder thread and under the second mentionedbinder thread.

l5. A Woven fabric as set forth in claim 2 in which all the weft threadsof the back ply pass over the binder threads, the weft threads cf thefacing ply being interwoven With said binder threads and serving to holdthe same tiglly against the wefts of the back ply.
